Blade assembly with lubricating elements
A blade assembly including at least one blade support and at least one blade element having a cutting edge portion. The blade support includes a base portion and a flat portion. The flat portion extends at an angle with respect to the base. The at least one blade is attached to the flat portion of the blade support. The blade assembly further includes a lubricating element. The lubricating element is attached to the flat portion and the at least one blade element.
1. A blade assembly comprising:
at least one blade element including:
a cutting-edge portion,
a base portion, and
a flat portion intermediate to a cutting edge of the cutting-edge portion and the base portion,
the flat portion extending at an angle with respect to the base portion, wherein the blade assembly further comprises
an incorporated lubricating element having an incorporated lubricating element first end and an incorporated lubricating element second end, the incorporated lubricating element being attached to the cutting-edge portion of the at least one blade element,
wherein the cutting edge portion extends from the cutting edge to an end opposite the cutting edge, the flat portion of the blade element further including a flat upper surface and a lower surface, the flat upper surface extending in a plane, the incorporated lubricating element first end being in direct contact with an upper surface of the cutting-edge portion, and the incorporated lubricating element second end being in direct contact with the flat upper surface of the flat portion only within the plane,
wherein the blade assembly further includes a curved bent portion disposed between the flat portion and the base portion, wherein the incorporated lubricating element does not directly contact the curved bent portion.
2. The blade assembly of claim 1 , wherein the flat portion and the base portion are built together to form a blade support, the cutting-edge portion being mounted on the flat portion of the blade support.
3. The blade assembly of claim 2 , wherein the incorporated lubricating element includes a first portion and a second portion.
4. The blade assembly of claim 3 , wherein the first portion is adjacent to the cutting-edge portion and the second portion is adjacent to the blade support.
5. The blade assembly of claim 3 , wherein the first portion is semi-circular and the second portion is rectangular shaped.
6. A head unit comprising:
a leading surface and a trailing surface defining a first shaving plane approximately tangent to these leading and trailing surfaces,
at least two blade assemblies according to claim 1 , wherein tips of the at least two lubricating elements define a second shaving plane, wherein an exposure of the cutting edge of at least one of the cutting edge portions is negative relative to the second shaving plane and positive relative to the first shaving plane or positive relative to both the first and second shaving planes.
7. The blade assembly of claim 1 , further comprising a second blade element comprising a second incorporated lubricating element, wherein one or more of the incorporated lubricating element and the second incorporated lubricating element comprises a water soluble component.
8. The blade assembly of claim 1 , wherein an entirety of the incorporated lubricating element is spaced apart from the curved bent portion.
9. The blade assembly of claim 1 , wherein the incorporated lubricating element extends continuously and uninterrupted along the surfaces of either the cutting-edge portion or the flat portion.
10. A blade assembly comprising:
at least one blade element including:
a cutting-edge portion,
a base portion, and
a flat portion intermediate to a cutting edge of the cutting-edge portion and the base portion,
the flat portion extending, in only one direction from the base portion, at an angle with respect to the base portion, wherein the blade assembly further comprises
an incorporated lubricating element, the incorporated lubricating element being attached to the cutting-edge portion of the at least one blade element,
wherein the cutting edge portion extends from the cutting edge to an end opposite the cutting edge, the flat portion further including an upper surface and a lower surface, wherein the incorporated lubricating element is in direct contact with both of the cutting-edge portion and the flat portion,
wherein the incorporated lubricating element extends continuously and uninterrupted along the surfaces of either the cutting-edge portion or the flat portion,
wherein the blade assembly further includes a curved bent portion disposed between the flat portion and the base portion, wherein the incorporated lubricating element does not directly contact the curved bent portion.
11. The blade assembly of claim 10 , wherein the incorporated lubricating element comprises a water soluble component.
